GEORGE A. vYOU'LT G, 0F DETROIT, MICHIGAN, ASSIGNOR T0 YOUNG BROTHERS COMPANY,

. F DETROIT, MICHIGAN, A CORPORATION 0F MICHIGAN INSULATING 'WALL STRUCTURE The present invention pertains to oven walls made up of metallic panels filled with A insulating material. The principal object of thickness walls of the panels to a considerable extent. In joining the panels together, the confronting end walls are retained at a distance from each other, and the intervening space is acked with a suitable insulating material. he joint proper consists of sheet metal portions projecting from each panel over a ortion of the adjacent anel and secured t ereto. Due to the per orated character of the end walls, the latter may be secured to the corresponding side walls by a metal-to-metal joint, thus avoiding the insertion of intervening insulating material as in my Patent No. 1,312,663 of August 12, 1919. The invention is fully disclosed by way of example in the following description and in the accompanying drawings in which- Figure 1 is a fraffmentary sectional view of a wall constructed the invention;

gig. 2 is a similar view of a modification; an

Fig. 3 is a detail of Figure 2 illustrating the extrusion of the filling material.

Reference to these views will now be had by use of like characters which are employed to designate corresponding parte throughout. v

The wall is composed of a number of panels, two of which are illustrated in F1 1 and desivnated by the numerals 1 an 2. Each suc panel comprises a pair ofsheet metal side walls 3 between winch is packed insulating material 4. The ends of this See-l tion must obviously be joined to form an enclosure.

and joined according to nection with Fi One end of each sheet 3 is formed with an I S-bend'7 which is offset towards the interior of the panel by means of a bend l8 in the sheet. The ends of a U-shaped end piece 9 are inserted between the two inward plies of the S-bend.

At the opposite end of each panel the ends of the panels are formed with return bends 14: received in the offsets formed by the bends 8. The ends of a U-shaped end piece 16 are received and secured in the return bends, and the member 16 encloses the member 9, leaving a space 10 therebetween. Itl will be seen that each panel is formed with S-bends at one end and with return bends at the other end. Adjacent panels are joined by inserting the S-bends between the return bends,

after positioning the end pieces 9 and 16,

and suitably fixmg the contacting parts toether. Any suitable means such as solder, orexample,

bends and for securing the end pieces 9 and 16 in the bends.

The end pieces 9 and 16 are perforated by means of slots 17 of considerable length in the dimension perpendicular to that illustrated in Fig. 1. The space 10 between the end walls is packed with heat insulating gasket material 18 whichmay be introduced 1n plastic condition. The material 4 is also extruded through the perforations 17 as indicated by the numeral 4 in Figure 3 and functions as a seal or gasket therein.

In the modification shown in Fig. 2, the S- bends 20 in the panel 21 have one ply thereof in the same plane as the face 22, the oiiset 8 of Fig. 1 being eliminated. Instead, the adjacent panel 28 has its face walls 24 offset outwar ly as at 25 and then prolonged and -:formed with return bends 26 which engages theI face walls 22. End pieces 27 and 28 are received in the. S-bencls and return bends' respectively as in Figure 1. Otherwise the construction is completed as described in conmay' be employed for securing the jolnts between the S-bends and return,

.Althoughy specific embodiments of the resent inventlon have been illustrated and escribed, it will be apparent that various all myterations in the details of construction may be made without departing from the scope of the invention as indicated by the appended claims.

What I claim is 1. In an insulating wall, a pair of insulating panels in end-to-end relation and having their confronting ends spaced apart, said end walls being perforated, and insulating material packed between said ends, one panel having a portion overlapping the other panel and secured thereto.

2. In an insulating wall, a pair of insulating panels in end-to-end relation and having their confronting ends spaced apart, each panel having sheet metal side walls one end of each Wall in one panel having an S-bend, the opposite ends of said walls having return bends, end pieces secured in said bends, one of said end pieces at said confronting ends enclosing the other, and insulating material packed between said end pieces.

3. In an insulating Wall, a pair of insulating panels in end-to-end relation and having their confronting ends spaced apart, each panel having sheet metal side Walls, one end of each wall in one panel having an S-bend, the opposite ends of said walls having return bends, end pieces secured in said bends, one of said end pieces at said confronting ends enclosinfll the other, and insulating material packed lbetween said end pieces, said end pieces being perforated.

4. In an insulating wall, a pair of insulating panels in end-to-end relation, each panel having sheet metal side walls, one end of each wall in one panel having an S-bend, the opposite ends o said Walls having return bends, end pieces secured in said bends, one of said end pieces enclosing the other, and insulating material in said panels.

5. A panel comprising a pair of arallel sheet metal walls having each an S- nd at one end of the panel, the opposite ends of said walls having return bends, end pieces secured in said bends and connectingsaid side walls, one of said end pieces being adapted to receive an end piece of the same size as the remaining end piece, and insulating material in said panels.

In testimony whereof I ailix m signature.
